Hello all you happy people.
Kay, so I've got a star-based office chair, and one of the wheels has popped off. The attachment itself is still fixed to the chair, it's just the actual wheel discs that have snapped off.
I've tried whacking them back into place, and it works for a few days and then it comes back off.
1) Are there replacement office chair wheel thingies available in DIY shops? 2) If yes, do I need to be wary of size differences, etc? Or are they standard? 3) I assume I have to replace the attachment, how does one go about removing that? So far I've tried upwards pressure, clockwise and counter-clockwise spinning, cursing, and Cajun voodoo. No luck.
